Light duty truck guys may often think about the true potential their pickup has to offer. The factory rating for the 6.6 liter Duramax turbo diesel engine is 365 horsepower and 660 pound-feet of torque, but how much of that is applied to the pavement? According to an in house dyno test by AEM with a 2007 Chevrolet Silverado 2500HD 6.6 liter Duramax, it produces 270 peak horsepower and 495 lb-ft of torque to the wheels. This shows there is a big loss in power getting to the wheels where you need it.

There is a solution for those wanting to get some of this power back. AEM manufactures air intake systems designed to add horsepower and torque. AEM's 21-9033DS, for 2007, 2008, 2009 and 2010 Chevrolet Silverado and GMC Sierra 2500HD and 3500HD models with a 6.6 liter Duramax engine can give your pickup truck noticeable power. Testing of this air intake on a 2007 Chevrolet Silverado 2500HD with a 6.6 liter Duramax engine showed an estimated gain of 15 horsepower and 35 pound feet of torque. AEM's air intake design created this power improvement by reducing restriction in the intake path and by bringing in cool oxygen rich air.

21-9033DS includes an AEM Dryflow synthetic air filter enclosed in a sealed air box unit, a high flow intake tube, all the hardware necessary for installation, and detailed instructions. A filter minder restriction gage is also included to indicate when air filter service may be required. A sealed air box design was created to block air heated from the engine and to focus bringing air in from the factory air inlet.

The Dryflow air filter in this cold air intake can be used for up to 100,000 miles before cleaning is needed, depending on driving conditions. Cleaning is as easy as spraying the designated AEM cleaner on the filter and rinsing it out. No oil is required, which is pretty convenient, so you can spend your time elsewhere on other important matters. To ensure the proper cleaning care of your Dryflow filter, pick up a bottle of AEM Dryflow cleaner and simply follow the instructions.

AEM cold air intake system 21-9033DS comes with a Lifetime Limited Warranty. It will fit the following Chevy/GMC 2500HD and 3500HD diesel trucks:
